MACHINE FOR TREATING LABELS AND APPLYING- THE SAME T0 CANS.

Specification of Letters Patent.

Patented Apr. 13, 1915.

Original application filed November 4, 1910, Serial No. 590,747. Divided, and this application filed November To all whom it may concern Be it known that I, FREDERICK H. KNAPP, citizen of the United States, residing at Westminster, in the county of Carroll and State of Maryland, have invented certain new and useful Improvements in Machines for Treating Labels and Applying the Same to Cans, 01": which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to an apparatus for treating labels and applying the same to cans and the like, the present application being a division of my pending application for Letters Patent filed Nov. 4, 1910, Serial No. 590,747 entitled Method of and machine for treating labels and applying same to cans.

it is common in the can labeling machine art to apply a coating of paste to the can body, which latter is moved into contact with the label whereby the latter is applied to the can, and it is also common to apply the label to the can by moving the latter over a previously pasted label, but in either case objections have arisen. primarily because of the fact that the label has been applied and'atlixed to the can immediately or shortly after the pasting operation, and before the label has had an opportunity to be come properly tempered after the moistening effect of the paste. It is well known that the labels, after becoming moistened or wet by the pasting, stretch and expand to a considerable degree, and as ordinarily applied this stretching takes places subsequently to the application of the label snugly and tightly about the can. The labels when thus applied to the can without previously being given a chance to swell, stretch or eX- pend, after becoming dry on the can present an unseemly appearance clue to wrinkling, and it often happens that the labels even become loose and at points separated from adhering contact with the cans.

The primary object of the present inven tion may be said to reside in a novel, economical and eliicient machine adapted in its operation to so temper the label, or to permit the same to become stretched and expanded after being moistened by the paste. and prior to its application to the can, with the obvious result that when applied the expansion of the label has occurred and the Serial No. 730,297.

reactionary contraction will take place subsequently to its application to the can, so that the label when completely contracted about the can will be found to have a snug and smooth fit about the can and will be free from the customary wrinkles.

It is appreciated that the invention is susceptible of a' large variety of embodiments and the accompanying drawings show one of the preferred embodiments which has proven satisfactory to a high degree, and will serve to illustrate the principles involved in the invention though it is not to be presumed that the same is to be limited to this particular embodiment.

More particularly the machine comprises a series of carriers which, in the instance illustrated, take the form of mandrels con nected one to the other, and which are adapted to contact with a body of paste to receive a coating therefrom and subsequently pick up a label, the latter being wound about the mandrels and thereby receiving its proper curve and coating of paste there from, though it is obvious in this connection that the label may be first pasted through other instrumentalities, and subsequently taken up by the mandrels. lVhen applied to the mandrels, the labels are carried to the point of application to the cans, which latter may be fed either by hand or automatic means, the former being illustrated in the drawing. During the travel of the carrier or mandrel from the point of pasting to the point of application of the labels mounted thereon to the cans, the pasting and can labeling mechanism being considerably removed one from the other, the label will have become first stretched, so that when applied to the can the subsequent contraction will cause it to snugly and firmly fit about the can, and when dried the same will be found to be devoid of wrinkles.

Though not essential, it is preferred, as above suggested, to form the mandrel or carrier of a curvature somewhat corresponding to the curve of the cans whereby a slight preliminary curve is given to the labels, and the latter will consequently readily conform to the curve of the can in the application. of the latter. In this connection, however, it is not desired to limit the application of the invention to curved cans, or in fact to anv particular kill-(l of cans, and it is to be borne in mindthat wherein the term canlis em ployed herein, this term is understood to include boxes and packages regardless of shape or character.

-,It is" also contemplated by the invention to make it possible to give to the mandrel or carriers an uninterrupted feedwhereby succeeding mandrels may be brought automatically into operative position relative to succeeding cans-to belabeled as the cans are placed in labeling position, with the result .that the labeling of the. cans may be continuous as is the case where the labels are- 7 1 a v c "pasted andVlmmedlatelyeapphed to the cans,

as in the usual practice. Hence it follows that-nodelay is occasioned by the preliminary tempering of the labels.

' I Other improvements and the j various novel details in the construction and arthe methodstated.

' -'--Figure ;1 is a side elevation of the ma chine, Fi 2 is an enlarged side elevation of the forward end of the machine, Fig. 3 is a front end elevation enlarged of the same, Figs. 4 6 and 7 are enlarged detailed ne s of thelabel carrying mandrel.

WV'ith more' particular reference to the drawings, a suitable platform or flooring l is provided, which constitutes a main support for the var ous parts of the machine.

Projecting upwardly from the support 1 adjacent what maybe called the front end thereof is a pair of separated overhanging bracket arms 2, while somewhat similar bracketarms 3 are-mounted adjacent the opposite end of the support. The bracket arms 3 constitute separated supports for a transversely extending shaft 4, which latter is mounted in suitable bearings 3) at the upper end of the bracketmembers 3. Se-

cured-to the support for the shaft 4 in any desired manner is avertically extendingrod 5, secured at itsupperend in any convenient. manner-to the transversely extending shaft '6. The bracket arms 2 also have secured thereto andconstitute separated supports for a transversely extending shaft? conveniently mounted in bearings 2*- at the upper end of said bracket arms 2. Projectmg between the shafts 6 and? and secured to each in any desired manner is a yertically inclined connecting rod 8, an additional support 9 for said shaft 2 and rod 8 being suitjfftbly' mounted on the support 1 as shown.

Adjacentvopposite ends of each of the shafts '4 and 6 are drive wheels conveniently taln'ng the form of sprocket wheels 9 and 10 respectively, while positioned upon the shaft 7 are relatively enlarged sprocket wheels 11, each of said sprocket wheels 9, 10 and 11 being freely rotatable on their respective shafts. Projecting between and mounted upon the said sprocket wheels are endless drive members shown as sprocket chains 12 and extending between the respective chains and secured thereto in any desired manner are supporting rods or shafts 13 upon each of which is loosely sleeved for rotation, a carrying member or mandrel 1 1- which in the instance illustrated. are round in cross section and hollow, and the diameter thereof preferably being larger than the diameter of the cans to which the label is to be ap- 'tudinally thereof, and in order to prevent lateral vibration of the mandrels during the travel of the chains, a suitable latch 15 1s provided, the same preferably comprising an elongated spring arm secured to the shaft 13, orthe connected link of the chain as shown and adapted at its, free end to automatically engage in a notch or recess 16 formed in the end of the mandrel 14 as the weight within the mandrel brings the latter into proper position. The recess 16 is relatively slight, so that the rotating action of the spring arm may be readily overcome, to permit of the free rotation of the mandrel in the operation of the apparatus to be more particularly referred to hereinafter. Also in the periphery of the mandrels is arranged a finger opening 17 conveniently midway of the ends' of the mandrel and to one side of the weight 14 in the latter, the purpose of which opening being to permit of the insertion of the fingers of the operator so as to grasp the edge of the label mounted on the mandrel, it being noted in this connection, as above mentioned, that the mandrel has a diameter in excess of that of the cans to be labeled, whereby, when applied to the mandrels in a manner to be described, one

end of the label will overlie a portion only of the opening 17 in the mandrel, thereby leaving an exposed edge or end of the label which as before explained may be readily grasped by the fingers of the operator, or other mechanical means which may be employed to strip the label from the mandrel and apply the same to the cans.

Positioned upon the support 1 in any desired manner is a receptacle 18 adapted to contain paste or other suitable adhesive, and mounted within the receptacle is a carrier or paste applying member, conveniently a roller 19, and preferably having a yieldable tread as of. felt 20. The periphery of the roller projects above the open top of the receptacle 18 and into the path of the man drels. To one side of the paste receptacle 18 and conveniently resting on the support 1 is a receptacle 21 adapted to contain a series of superimposed labels 22, the said receptacle being preferably provided with a follower of any of the approved types commonly employed in the can labeling machine art for automatically feeding the labels in the receptacle whereby to position the uppermost one adjacent the open top of the receptacle, and it is not deemed necessary to show such a follower in the present case. The sides and forward end of the label receptacle may be cut away at 23, so as to expose an end of the uppermost label, whereby it may be readily taken up by a mandrel as it is moved past the same by the carrying chains 12 previously described.

Also positioned upon the support 1, adjacent the rear end of the label receptacle is what may be termed a label ironing or presser member, the same preferably comprising a block or support 24 upon which is mounted a yieldable pad 25 of any desired material, suitably felt, the purpose of which being to engage the labels which have been applied to the carrier or mandrel, as the mandrels move past the ironing member 24, so as to smooth the label about the mandrel and to insure the contact of the label with the pasted area of the mandrel whereby the label will receive its supply of paste from the mandrel.

Preferably a common operating means is employed for the paste applying member 19 and the mandrel carrying chains 12, the same comprising a drive shaft 26 suitably supported in any desired manner as by hanger brackets projecting downwardly from the flooring 1, said shaft adapted to be driven from any suitable source of power, as by a belt 28, engaging a pulley 29 fixed to the shaft 26. Secured to the shaft 26 for movement therewith is a sprocket wheel 30 and also a gear pinion 31. A chain 32 mounted upon the sprocket wheel 30 is arranged to engage a sprocket wheel 33 secured to the shaft 34 of the paste applying member 19, the wheel 33 being arranged without the receptacle 18, as shown. A vertically extending rotatable shaft 35 having adjacent one end a worm 36 and adjacent its opposite end a bevel pinion 37 is mounted in suitable bearing sleeves 26*, the same sleeves being respectively on one of the bracket arms 3 and the support 1. The bevel gear 37 is adapted to mesh with the bevel gear 31 on the shaft 26, while the worm 36 is arranged to mesh with a worm gear 38 having a'fixed connection with one of the sprocket wheels 9 which latter has a fixed connection with its companion sprocket wheel 9 as by a connecting sleeve 39 loosely mounted on the shaft 4. In this way, the sprocket wheels 9 are driven by the drive shaft 26 to impart rotary movement to the chains 12 and the connected mandrels, and likewise the paste applying member 19 is driven from said shaft 26 by the chain 32, but it is noted in this connection that the movement of the chains and their connected mandrels is much slower than that of the paste applying member, this for the reason that it is desired to give the labels which are applied to the pasted mandrels ample time to receive the paste therefrom and become stretched and expanded during the travel of the chains 12 to the discharge end of the chain travel. The relatively slow movement of the mandrel carrying chains is also of importance when the rotary paste feed 19 is employed, whereby as the mandrels contact with the paste feed the rapid rotation of the latter will apply a coating of paste entirely around the mandrels, as the carrying chains slowly move past said pasting member.

From reference to Fig. 1 is will be seen that the upper surface of the presser pad member, the label receptacle and the periphery of the paste applying roller 19 are in substantially the same horizontal plane, and also that the bottom of the sprocket wheels 4 and 11 are in substantially the same horizontal plane whereby to space the chain carriers 12 a sufficient distance above the paste applying member 19, label receptacle 21 and presser pad 24 to permit the mandrels in the travel of the chains to contact with said parts.

The operation of the parts thus far described may be set forth as follows: It being assumed that paste has been placed within the receptacle 18, and that a supply of labels has been positioned face downward in the receptacle 21, traveling movement of the chains 12 about the sprocket wheels is effected through the sprocket wheels 9 which as previously described have gear connection with the drive shaft 26. Likewise rotary movement is imparted to the paste applying member 19 by the drive shaft 26 through the chain 32. The weights 14 within the mandrels bring a predetermined portion of the periphery of the latter lowermost, while the opening 17 in the l mandrel will be slightly to the right side 7 of the mandrel as the latter move into con tact with the paste applying member 19. As soon as the mandrel engages the paste applying member, the relatively light spring arm or latch 15 is automatically released from the recess 16 at the end of the mandrel, the mandrel will be rotated about the periphery of the paste roller 19 by the latter, and recelve a coating of paste. Uponbeing released from paste applying member 1-9 jby the continuing movementyof the chains 12,;the mandrel will beemoved by thejweightthereininto proper position to engage the exposediend ofjthe uppermost lfabel in the receptacle'21, which label will be taken up by the mandrel during. the

traveling movement of the latter. over the v ;upper edge of the "receptacle whichlatter into engagenientwith the presser onironsmoothly pressed upon, the mandrelby the rotation ofithe latter, the spring arm having been released. by the. engagementlofthe .mandrelwithrthe presser member 24. The

label at jthis point jvill .be, seentofit snugly end adjacent the weighted portien'. ofzthe periphery of the mandrel while the opposite end will overlie a portion of the finger opening 171 in the mandrel, the mandrel being, of asize larger than the cans to which the labels are tojbe applied, whereby a-label will not goicompletelyaround the periphery. "of the mandrel'but willfileave an exposed edge which overlies the opening 17in the mandrel to permit of the label to be stripped. from the mandrel; for application. to the can. 'Upon leaving the presser or ironing member the mandrel-due to its weight will be moved into positionnto be engaged by the spring latch'l5-whereby during the travel of the mandrel with the chain lateral vibration is prevented. The travel of the chain isat such a'speed and of such a duration as to permitthe labels appliedto the mandrels on said chains tozbecome practically s'et or tempered-by the time the mandrel reaches its discharge position, which as shown is at the front end of the machine and conv nie'ntly m e up of the parts about to be described. 1 r 1 2 are angle bracket members t0, the upright Secured'to the'overhanging bracket arms vertical portions thereof have slotted ways 4E0 adapted'forthe reception'of a transversely extending, rod ll extending between the respective bracket members 40'- which saidrod 41 hasmounted thereon'for rotary movement a presser roll 42 which is nor? mally. positioned adjacent the upperend of the slot-ted ways H) by reason of the pres sure exerted by the spiral springs-43. An actuating member, conveniently taking a 'U- shaped form and constituting a treadle 44. is provided and adapted to be actuated by the footiof theoperato'r, thevertically extending arms 44? of the treadle being sej V about the periphery of themandrelwith one 25.

cured to the opposite ends of the rod 41, as

clearly shown in Fig. 8. The bracket members' 40 are conveniently enlarged at 40" and constitute bearings for opposite ends '1 of a pair of laterally spaced rollers 45, the shaft 45* for one of said rollers being'con- 'venientlyi extended at one end beyond the adjacent bracket arm 40 and having secured thereto: an operating handle 46 whereby 1- the '-'connected v roller is positively driven. The separated rollers 45 together constitute 'a pocket or support for a canto be labeled,

which maybe placed in said pocket and beplication offthe labels to the can, the operatorgrasps the exposed edge of theglabel on the mandrel whichoverlies the opening the mandrel and applies said edge to the can which has been placed in a pocket formed by the rollers 45. The can is thereupon vgiven a rotary movement by rotating the handle 46 which rotates one of the roll- 61'845, and said canm its rotary movement will. continue to draw the label from the imandrel' and wind thesame about its periphery. It will be observed that that end of 'tlielabel lastleaving the mandrel will constitute the lap endof the label on the ;can and since'said lap end has a pasted surface from end. to end it will overliethe' other end of the labelas is obvious. At this time the operator places his foot upon the treadle actuating member 4-4, and by exerting downward pressure thereon will move the presser member 42 against the action of the springs l3 downwardly until said presser member firmly engages the labeled can, and when in this position the rotation of the labeled. can is continued by the operator through the medium of the handle 46 and the label will thereby become firmly afiixed to the can.' It has been seen that prior to this application to the can the label has become properly tempered. The label upon the canwill be practically devoid of further stretching and by subsequent contraction when dry it will be firmly and smoothly tween the brackets 41) by the hand of the op- 1 .erator or otherwise. a

1-7 in the mandrel, and strips said label from affixed to the can andin a manner devoid of the customary wrinkles.

While various instrumentalities may be employed in aflixing the'tempered labels to the cans, that shown is an exceedingly simple and economical construction and permits of a quite rapid labeling of the cans since the operator may pick up the can and position it with his right hand and .while so positioning the can strip the edge of the label from the mandrel and engage the same With the positioned can With his left hand and so soon as the label is so engaged the operator with his right hand Will impart the necessaryirotation to the can through the medium of the actuating handle 46, and at the proper time the treadle 4st Will be depressed by the foot so as to bring the presser roll into position While the rotation of the can is continued through'the means of the handle 46 and connected roller 45.
